Answer:

1) Reflect point (-2,-8) across the x-axis. This reflection has a rule

(x,y)→(x,-y).

Thus,

(-2,-8)→(-2,8).

2) Reflect point (-2,8) across the y-axis. This reflection has a rule

(x,y)→(-x,y).

Then

(-2,8)→(2,8).

3) The image point (2,8) is placed in 1st quadrant.

Quadrant I
Answers. Sample Response: If (−2, −8) is reflected across both axes, it will be located at (2, 8), which is in Quadrant I. When a point is reflected across both axes, the signs of both the x- and y-coordinates change.

In a distribution, a score of X=60 has a z-score of -3.0.. A score of X=85 has a z-score of 2.0. What are the mean and standard
never [62]
The formula for a z-score is
z=\frac{X- \mu}{\sigma}
We don't have μ, the mean, or σ, the standard deviation.  We can, however, set up a system of two equations with the information we do have.  We know:
-3=\frac{60- \mu}{\sigma} \text{ and } 2=\frac{85- \mu}{\sigma}
We can make this look more like a "typical" system of equations by cancelling the fractional part of each equation.  We do this by multiplying the bottom of each equation by σ:
-3*\sigma=\frac{60- \mu}{\sigma}*\sigma \text{ and } 2*\sigma=\frac{85- \mu}{\sigma}*\sigma
\\
\\-3\sigma=60- \mu \text{ and } 2\sigma=85- \mu
Now we'll get the variables on the same side of the equation.  We'll do this by adding μ to both sides:
-3\sigma + \mu=60- \mu + \mu \text{ and } 2\sigma+ \mu =85- \mu + \mu
\\
\\-3\sigma+\mu=60 \text{ and } 2\sigma+\mu=85
Now we'll write this vertically:
\left \{ {{-3\sigma+\mu=60} \atop {2\sigma+\mu=85}} \right.
We will "eliminate" μ by subtracting the bottom equation:
\left \{ {{-3\sigma+\mu=60} \atop {-(2\sigma+\mu=85)}} \right. 
\\
\\-5\sigma=-25
Divide both sides by -5:
\frac{-5\sigma}{-5}=\frac{-25}{-5}
\\
\\\sigma=5
Our standard deviation is 5.  Substituting this into our top equation we have:
-3(5)+μ=60
-15+μ=60
Cancel the -15 by adding it to both sides:
-15+μ+15=60+15
μ=75
Our mean is 75.

Suppose that the cost of a rental car is $65 for a week plus 0.15 per mile driven.
IceJOKER [234]

You have the following equation for the cost of renting a car for x number of miles driven:

y = 0.15x + 65

If you travel 70 miles, then, x = 70 and you obtain for the cost y:

y = 0.15(70) + 65

y = 10.5 + 65

y = 75.5

Hence, the cost of renting a car to drive 70 miles is $75.5

Find the length of the unknown side. Round your answer to the nearest tenth. (4 points) Image of a right triangle with a leg lab
Anika [276]

using pythagorean theorem

a^2 + b^2 =c^2

a^2 +8^2 =14^2

a^2 +64 = 196

subtract 64 from each side

a^2 = 132

take the square root of each side

a^2 = sqrt (132)

a=11.48912529

a =11.5
